'bound-details allows for left/right/left-broken/right-broken subproperties.
Possible subsubproperties (read by ly:line-spanner::print) are documented here:
http://lilypond.org/doc/v2.19/Documentation/notation/spanners#using-the-line_002dspanner_002dinterface

Please specify which problem(s) you see with you're example-code in
the future. ;)

My guessing below:

\version "2.19.81"

ottavaUp = {

  \once \override Staff.OttavaBracket.stencil = #ly:line-spanner::print
  \once \override Staff.OttavaBracket.bound-details =
    #`((left . ((Y . -0.2)
                (attach-dir . ,LEFT)
                (padding . 0)
                (stencil-align-dir-y . ,UP)))
       (left-broken . ((Y . -0.2)
                       (text
                         .
                         ,#{ \markup \bold \concat { "8" \hspace #0.25 } #})
                       (padding . 2.5)
                       (attach-dir . ,RIGHT)))
       (right-broken . ((text . #f)
                        (padding . 0)))
       (right . ((Y . -0.2)
                 (padding . -0.75)
                 (attach-dir . ,RIGHT)
                 (text . ,#{
                    \markup
                    \override #'(full-length . #f)
                    \override #'(on . 0.15)
                    \override #'(off . 0.5)
                    \override #'(thickness . 1.8)
                    \draw-dashed-line #'(0 . -1.5)
                  #}))))

  \once \override Staff.OttavaBracket.left-bound-info =
     #ly:line-spanner::calc-left-bound-info-and-text
  \once \override Staff.OttavaBracket.right-bound-info =
     #ly:line-spanner::calc-right-bound-info
  \override Staff.OttavaBracket.style = #'dashed-line
  \override Staff.OttavaBracket.dash-fraction = #0.2
  \override Staff.OttavaBracket.dash-period = #0.7
  \override Staff.OttavaBracket.thickness = #1.5

  \ottava #1
  \set Staff.ottavation = \markup \bold \concat { "8" \hspace #0.25 }
}

\relative c' {

  \ottava #1
  a'''1^"Default" a a a \break
  a a a a4 \ottava #0 r2. \break

  \ottavaUp a^"Modified" a a a \break
  a a a a4 \ottava #0 r2.
}

\layout {

}
